ROTARY MOTOR.

Specification of Letters Patent.

Patented Oct. 9, 1906.

Application filed May 31, 1905. Serial No. 262,998-

To all whom it may concern:

Be it known that we, LOUIS ERRANI, a resident of 14 Rue Olauzel, andLoUIs GUERIN, a resident of 47 Rue Ramey, Paris, France, citizens of theRepublic of France, have invented an Improvement in Rotary Motors, ofwhich the following is a specification.

This invention relates to a rotary motors comprising a plurality ofcylinders secured for rotation about a common axis and each containing aweight and means for moving said weights to cause displacement of thecenter of gravity.

In the illustrated embodiments of our in vention a plurality ofcylinders containing heavy weights are arranged at regular intervalsaround the axis of the motor, with each cylinder extending in bothdirections for a considerable distance beyond said axis, and connectionsare provided whereby each weight is raised by pressure when the end ofthe cylinder containing it reaches the lowest point of travel, theraised weight being moved to the then upper end of the cylinder andabove the axis of the motor.

In the accompanying drawin s, Figure 1 I is a cross-section of one formof motor embodying our invention. Fig. 2 is a longitudinal section ofsuch form of motor, and Fig. 3 especially illustrates details of thevalves for controlling supply of pressure to the cylinders and exhaustthereof.

The frame supporting the motor may comprise uprights Z Z, whichnon-rotatively support the alined axles X. A motor-body, such ascylinder m, is mounted to rotate concentrically around the axles X. Atone end said body is shown as rigidly and adjustably secured by screws 9to a bored block Z, surrounding a sleeve upon the short axle X, and atits other end the body m is rigidly and adjustably secured, also byscrews 9, to a tube h, surrounding two rings arranged end to end and oneof which, 7c, is secured against rotation, the other ring moving withthe tube h. Both rings surround a sleeve upon the longer axle X.

The body m is provided with cylinders a, b, c, and d, of cast-iron orother material, and arranged, preferably, at regular intervals aroundand longitudinally of the cylinder. Each cylinder extends through andprojects at both ends for a considerable distance from the body m, andeach cylinder is provided with an opening or port at each of its ends,and each port communicates with a pipe or tube. The various pipes justreferred to pass through the tube It and lengthwise of the ring rotatingwith said tube.

Freely-slidable weights f, f f andf are fitted one within each of thecylinders a, b, c, and d. Said weights maybe of any material, such assolid or hollow castin s. If hollow, they maybe entirely or partly ledwith lead, or even mercury. In the instance illustrated each weight isabout half the length of the cylinder wherein it works, though suchproportions are optional.

The ring 7c, secured against rotation as aforesaid, is provided with asup ly-pipei and an exhaust-pipe c, the former deing connected with acock 1), leading from the source of steam, gas, or other pressure. Theports in the ring is, from which the pipes 11 and e lead,dare, as shownin Fig. 3, slightly elonate g In the operation of the motor illustratedthe cylinders a, b, c, and d are successively presented at the lowestpoint of their travel, with the weights f f j in the ends thereof thenlowermost, and at or near the point mentioned pressure is supplied tothe cylinders, so as to shift or lift the Weights to the ends of thecylinder then uppermost, the proper supply and exhaust connections beingestablished. As shown in Fig. 2, when the pipes connected with therespective ends of a cylinder come into register with the pipes in thefixed ring 7c pressure passes by way of pipes i into the lowermost endof cylinder a, and the weight f is raised or forced to the uppermost endof the cylinder, from which air or other medium is exhausted by way ofpipes c. The same is true of each of the cylinders as it reaches thepoint mentioned, and as the weights are raised every time they theyreach the lowermost point of their travel, it follows that (with themotor illustrated) there will always be a preponderance of the weightsat one side of the axis of the motor as long as pressure is supplied androtation of the motor will continue.

Itwill be obvious that the pipes entering the opposite ends of thecylinders a, l), c, and d serve alternately as a supply-pipe and as anexhaust-pipe.

What we claim is In a rotary motor, a cylindrical rotatable motor-body,a pluralityof cylinders'ex- I In testimony whereof We affix oursignatending through and pro3ecting at both tures in presence of twoWitnesses.

their ends from said body, and arranged at intervals around andlongitudinally of said body, slidable Weights Within the secondnamedcylinders, and connections for causing the Weights Within the cylindersto shift above the axis of the body.
